The length of rectangular sheet of paper is 24 cm more than the breadth and perimeter of the rectangular sheet is 128 cm. Find the length of the rectangular sheet. |
20 cm 44 cm 48 cm 34 cm |
44 cm |
We know that, Perimeter of a rectangle = 2(length + breadth) We have, Length of rectangular sheet = Breadth + 24 cm Perimeter of rectangular sheet = 128 cm Let the breadth of the rectangular sheet = a cm. Then, the length of the rectangular sheet = a + 24 cm Perimeter of the rectangular sheet = 2(length + breadth) 128 = 2(a + a + 24) 128 = 4a + 48 4a = 80 a = 20 The breadth of sheet = 20 cm. Length of sheet = breadth + 24 = 20 + 24 = 44 cm. |
